Wetting penetrant WE 3650 is a highly effective additive with several notable features and applications in the coatings and ink industries:

Physical Properties:

It is a clear, colorless to slightly yellow liquid. This visual characteristic makes it unobtrusive and easy to handle during various industrial processes.

Wetting Performance:

It is an extremely efficient wetting agent. It can rapidly reduce the surface tension of liquids, enabling them to spread evenly and thoroughly over a wide range of substrates. This property is crucial in applications where complete and uniform wetting of the substrate is essential for achieving optimal results. For example, in water-based coatings and inks, it helps to ensure better adhesion of the coating or ink to the substrate.

Foam Stabilization:

One of the remarkable features of WE 3650 is its low foam stabilization. This is highly beneficial in industrial processes as excessive foam can cause various problems such as interference with the application process, inaccurate dosing, and difficulties in quality control. The low foam property of WE 3650 allows for smooth and efficient operation.

Applications:

In the coatings industry, it is widely used in water-based coatings such as architectural coatings, automotive OEM coatings, general industrial coatings, exterior and interior wood coatings, etc. It can improve the leveling effect of the coating, reduce the occurrence of surface defects like craters and pinholes, and enhance the gloss and uniformity of the coating film.

In the printing industry, it is an effective additive for water-based inks. It can enhance ink transfer and adhesion, resulting in sharper and more vivid printing results.

Problem Solving:

WE 3650 can be effectively used in lacquers or inks that have problems related to substrate wetting or cratering. By addressing these issues, it helps to improve the quality and performance of the final product.
